Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528662, here are decompositions:
- 29 + 31528633 = 31528662
- 41 + 31528621 = 31528662
- 83 + 31528579 = 31528662
- 89 + 31528573 = 31528662
- 103 + 31528559 = 31528662
- 131 + 31528531 = 31528662
- 163 + 31528499 = 31528662
- 211 + 31528451 = 31528662
Showing the first eight; more decompositions exist.
